Please see the attached photo for details. This unit is powered on, but I haven’t been able to check its operation. The light came on when I turned it on. Fast forward and rewind worked, but playback wouldn’t work. Also, I was able to open the cassette once, but the left side wouldn’t open the second time. It probably needs maintenance before it can be used. I think there’s some kind of problem. We cannot change the address once the order has been placed. We are happy to assist you.
